Structures that produce and release hormones into the blood are known as endocrine glands.

Here are the steps that explain how these glands work:

1. Endocrine glands are ductless glands that produce and secrete hormones directly into the bloodstream, rather than through a duct.

2. These glands include the pituitary, thyroid, parathyroid, adrenal, and pineal glands. The pancreas, gonads (ovaries and testes), and placenta also have endocrine functions.

3. Each gland produces specific hormones that target certain organs or tissues in the body.

4. The hormones are released in response to signals from the body. For example, the pancreas releases insulin when blood sugar levels rise.

5. Once released, the hormones travel through the bloodstream to their target organs or tissues, where they bind to specific receptors and trigger certain responses. For example, insulin triggers cells to take in glucose, which lowers blood sugar levels.

6. The endocrine system works closely with the nervous system to maintain the body's internal balance, or homeostasis.
